Referring first to Figs. 1, 2, 3, 4 and 11, the frame of the machine, in which or on which the various parts and rotatable and movable members are supported, includes a pair of side plates [0 and II mounted on a suitable base I4, which cross rod 2 I is shown in Figs. 1-4.

A delivery chute, indicated in general by the reference character I2, has its discharging end supported by the side plates in the upper part of the machine. Y The newspaper sections which are to be inserted or stuffed into the othersections, as, for example, the Sunday magazine sections, are delivered to the machine via this upper chute I2. shown,.and which need not be described since it does not constitute part of the present invention, these newspaper sections are delivered into the chute I2 with their horizontal or mid-page foldsat the bottom, and are moved along the chute I2 from left to right, as viewed in Figs. 1 to 4, so that as fast as the sections are removed By suitable well known means, which i not one by one from the ['dGliVElY end of the chute by in the chute pending their removal serially by the machine.

Another similar chute I3, extending in the opposite direction, has. its discharge end supported by the side plates l0 and II in the lower and opposite position as indicated in Figs. 1 to 4. Through the medium of this second chute I3 the other newspaper sections, for example, the main news sections, into which the previously mentioned sections A are to be inserted or stuifed, are delivered to the machine. with the newspaper sections A for the upper chute I2, suitable means (not shown) causes the outer newspaper sections, designated by the reference character B in Figs. 1 to 4, to be delivered into chute I3 with their horizontal or mid-page folds at the bottom, and to be moved along in chute I3 from right to left (as viewed in Figs. 1 to 4). A flange H, at the bottom of the .delivery end of the chute I3, prevents the folded bottom ends of the newspaper sections B from being pushed fromthe chute I3 intothe machine, and separate means, to be described later, restrain the upper portions of these sections B from moving into the machine except as each section in turn is taken up by the mechanism in the manner later explained.

A pair of pick-up cams 20 are keyed or otherwise secured to a driven shaft 22. These cams are identical in shape and size and are identically positioned. The pick-up cams 20 are specially shaped, their shape being clearly shown in Figs. 1 to 7, and these cams are each formedwith a rim hook 23 extending into their cut-away portion, which rim hooks 23 are adapted to pick up a newspaper section coming into their path. The direction of rotation of these pick-up cams 20 is clockwise as viewed in Figs. 1 to '7 inclusive.

1 A pair of squeeze rolls 24 are mounted above and in vertical alignment respectively with the As in the case 4 pick-up cams 20. Each squeeze roll 24 is mounted at one end of a pivoted bracket 25, the brackets 25 being pivoted on a stationary bar 26 extending between the side plates I0 and II. .A pin 21 is secured to each bracket and extends upwardly from the bracket. The pins 21 extend through holes in the shaft 28 and are slidable up and down through the shaft 28. The upper end of each pin 21' is threaded and a nut 29, adjustably mounted on the top of each pin 21, limits the downward movement of the pin and thereby limits the downward swing of the bracket 25 when the squeeze roll is not contacting the periphery of the cam 20. A compression spring 30 is carried on each pin 21 and held under compression between the bracket 25 and the shaft 28. Thus these squeeze rolls 24 will engage and ride on the outer peripheries of the cams 20 as soon as the cams turn sufilciently to enable their circular peripheries to be engaged by the squeeze rolls, and the nuts, 29 can be adjusted so that the squeeze rolls 24 will bear against the periph: cries of the cams 2B with adesired limited amount of pressure so that a newspaper section after being brought into engagement with the pick-up cams 20 will be pulled along between the cams and their squeeze rolls as illustrated by the newspaper section A in Figs. 2, 3 and 7. Preferably the peripheries of the cams 20 and their companion'squeeze rolls 24 are knurled or roughened slightly to enable them to pull the newspaper sections along more easily.

In order to cause the bottom edge or fold of each newspaper section A to be moved out from the end of the chute I2 and positioned in the path of the rotating pick-up cams 20, as shown in. Figs; 1 and 6, I provide a partially-rotating and oscillating cam roller I8 which is arranged and constructed in the special manner now to be described.

This cam roller I3 (see also Fig. 10), has a.

longitudinally-extending cam portion which pref erably .is provided with recesses, into whichrecesses surface-engaging elements 32 of rubber or the newspaper section to be pulled a short distance upwardly. This upward pull on the paper will lift the bottom fold of the newspaper section up and out from the flange I5 and will swing the fold of the newspaper section into the path of the rotating pick-up cams 20 as illustrated by the newspaper section A in Fig. 6. The rotating cams 20 will engage this portion of the newspaper section and press this portion against the squeeze rolls 24. When this takes place the newspaper section A will then be pulled away from the chute I2 and from the next newspaper section in .the chute I2 and will occupy the successive positions illustrated in Figs. 2, 3 and 4.

If, when the newspapersection A is pulled away from the other newspapersections in the discharging end of the chute I2 by the pick-up cams 2G and their associated rolls 24, the outer portion of the newspaper section A were to be pulled over the surface-engaging elements 32 on the cam roller I8 the rubbing of the paper over the elements 32 might blur some of the printing on the paper and would at least cause some wear on the surface of the contacted paper. In order gee-gees td preventthis the movement of the oscillating camroller l8is so synchronized that asthenewspaper'sect'ion is seized and pulledb'y the"pick--- up camszn and their squeeze rolls 24, the oscil-' lating roller P8, with its engaging elements 32'} will move in counter-clockwise direction at such speed that the speed of movementof' the engag higfsu'rfaces of the elements 32 will 'bethe'same as the speed with which the engaged paper moves. This counter-clockwise partial rotation" of the" cam rollerl ficontinues until the'elements 32 have moved down faren'ough t'o nolo'nger contact the Thus by having the elements 32"move'with respect to the paper at the surface of the paper.

same speed as the paper, untilthey'no longenare in engagement with the paper, rubbing action" between the elements 32 and the engaged paper surface is substantially eliminated. This is'one of the special featuresof my invention. When the elements 32have'been rotated out ofcontact are secured, has a disc 33] attached to one end" beyond the side plate ll. of the machine. The disc 33 carries a crank pin 34" to which a rack bar 35 is attached. The teeth of the rack bar engage a pinion .36 secured to an outer end of the shaft of the cam roller H3. The rackbar 35 slides in a channel provided in a housings! which is rotat ably mounted on the shaft of the cam roller l8 and which housing encloses the pinion 36. The size of the pinion 36, the distance of the crank pin 34 from the axis of the disc 33, and theposition to which the pick-up cams are secured on end shaft 22, are'so arranged thatthe elements 32 will move upwardly in clockwise direction: (as viewed in Fig. 5) when the cut-out portion of the:

pick-up cams are approaching the squeeze rolls- 24. This upward movement of the elements 32,. as previously mentioned, by pulling the opposed face of a newspaper section A upwardly, lifts the.

horizontal fold.- at the bottom. of the newspaper section out into the pathof the rimhooks 23 of the pick-up cams 2!]: After this has taken place and the newspaper section A is in the position illustrated in Fig. 6, the elements 32 cease their upward movement while the rim hooks 23 approach the squeeze rolls 24.-- Before: starting on its downward stroke, the rack baracts to tilt thecam roller is in counter-clockwise direction and this preliminary downward movement of the elements 32 allows sufficient slackto' develop in the outer portion of the newspaper section A between the elements 32 and the bottom fold, to enable all the sheets of the newspaper section'A to lie in contact with each other as therim hooks 23 proceed to pinch. the bottom fold against thesqueeze rolls 24. Then the'rack bar 35'starts its downward travel causing the: e1e-= merits 32 to move downwardly and rapidly in counterclockwise direction from the: position of Fig; '6' to the position of Fig. 7. The elementsx32 during this stage move at. substantially: the same speed as the newspaper section,.-.as previously:

mentioned, untilthe elements-32 reach: their lower est position where they are out-of" contactwith thefnewspaper section.

When the newspaper section has nearly completed its travel between the cams 20-'*andthe squeeze rolls 24 itis engaged by a pair of driven" rolls- 38" and their cooperating squeeze ro1ls-3'8 (Figs. 3 and 4). While the driven rolls 38 are of" approximately" the same diameter as the pickup cams 20; the shaft to which the rolls 38 are secured and the shaft to which -the-pick-up-" cams 20 are secured are-connected by gear means" in such manner that the surface speed of the rolls 3'8wil'l 'be considerably greater than that of the cams 213, so that the travel of the newspaper sec-- tion A will be speededup to enable the section" A to be dropped into the opened up outer news paper section B at theproper moment.

The squeeze'rolls 39, like the squeeze rolls-241 are mounted on the ends of pivoted brackets 4B:

Pins ll, secured to the bracketsdfl, are longitudinally slidable in holes through a shaft 42- ahdj have nuts 43'mounted on the upper threaded ends beyond the shaft 42. A coil spring 44 is mounted on each pin 4! and is held under slight compres--- sion between the bracket All and the shaft '42; en* abling the pressure of the squeeze rolls 39 agains't the driven rolls 33 (and against the newspaper" section A being moved'along by the rolls saw be'adjusted as desired.

A plurality of guides 10 (Figs. 1 to 4) aid indl recting the course of the newspaper section A tion A to drop into an outer newspaper section B" which is delivered from thelower chute l3 and which is opened upto receive the newspaper sec-" tion A in a manner now to be explained.

A push-bar 15' (Figs. 11, 14 and 15), extending:

in atransverse plane and pivoted on a pin 46'- mounted'ona bracket 57, which bracket is se cured on the outer face of the side plate It, has a hinged inner end @5 extending a short distance into the machine and so positioned and located as to contact an upper corner along a vertically folded edge of an adjacent face of an outer newspaper section B to be removed from the delivery end of the chute l3. Ari-engaging element 48:. of rubber or other suitable material, is mounted on the adjacent face of the inner end portion 45 so as to be capable of frictional engagement with the upper corner and the adjacent face of the newspaper section B. The outer end of the pivoted bar 45- (Fig. 14) is connected bymeans of a slotted link .19 to a rotated disc 5|, the

slottedlink 49 being attached to the disc 5 by a crank pin 53; A coil spring 63' (Fig. 14) tendsto pull the outer end of the bar 45 downwardlyto the extent permitted by the link 49 but therotation of the disc 5! and upward movementm? the link 59 moves the bar 45 against the force" of the spring 63. A fiat spring 64 normally holds the inner end 45 of the bar 45 in the same plane as the main portion of the bar 45. The disc 51 (see also Fig. 16) is connected by suitable bevel gears to a driven shaft 52 and the shaft 52 1s? connected at its opposite end to a gear trainso that the shaft 52 is driven from th single main drive for the entire machine.

The hinged inner end 45 of the bar 45 carries a pin 89 (Figs. 14 and 15), the outer endoi which rides in a curved groove 8! formed in the" bracket 41. The bottom of the groove 8| through out most ofits' extent is parallel to the face off the bracketl ll, but atthe lower endoflth ;gr vg th bottom slopes rather abruptly towards the.

face of the bracket 41 as viewed in Fig. '14. Thus when the hinged inner end 45 is moving downwardly (thus in counter-clockwise direction as viewed in Fig. 14), and approaches the end of its downward travel, the pin 80, bearing against the bottom of the groove 31, pushes the hinged end 45' against the force of the spring 54 and out from the plane in which th remaining or main portion of the bar 45 moves. The reason for this will be explained later.

An arm 53 (Fig. 14) is pivoted on a stub shaft 55 mounted on the bracket 41, the arm 53 being spaced from the bracket ll by a suitable spacing sleeve (not shown) so as to move in a plane parallel to the face of the bracket 41 (see also Fig. 16). The disc (Fig. 14) has a peripheral cam surface against which the bottom end of the arm 53 is held by means of the coil spring 55, one end of the coil spring being attached to the side plate H and the outer end or the coil spring being attached to'the outer end of a bracket arm 53 rigidly mounted on the arm 53 and extending outwardly from it, the outer tip being bent at a suitable angle to keep the coil spring spaced from the arm 53. An inwardly extending wedge-shaped finger 55 (Fig. 16) is mounted on the upper end of the arm 53. The peripheral cam surface of the disc 5! is formed with a sudden drop or shoulder 51 (Fig. 14) and when the cam-follower lower end of the arm 53 passes over this shoulder 57 (the disc 5] being rotated in counter-clockwise direction as viewed in Fig. 14), the finger 56 is suddenly thrust inwardly through a suitable opening provided in the side plate H, the finger 55 then occupying the position illustrated in Figs. 14. and 16.

A supplemental finger 53 (shown most clearly in Fig. 16) is pivotally mounted in the main finger 56, as shown in Fig. 16. This supplemental finger 58 is in the form of a bell crank and is normally held in closed position by-a compression spring 55. An engaging portion 60 of the side plate I! is so arranged as to engage the projecting arm of the supplemental finger 58 as the arm 53 and the main finger 55 reach the limit of their inward movement. The purpose of the main finger 55, supplemental finger 58 and bar 55 with its engaging element 58 will be explained presently.

A driven shaft 52 has a finge 5! (Figs. 1 to 4), with an outer curved surface which is so arranged as to be capabl of contacting and partially rotating a freely-mounted roller 53 mounted at one end of a pivotally-supported arbor 55. The arbor 64 is pivotally supported at its central point on a shaft 65 and is held between an ad justable stop 61, carried in a cross bar, and a small cam secured on a rotating shaft 56. The cam of shaft 55 engages a flat spring 58 in a recess in the corresponding end of th arbor 54. Both the shaft 55 and the shaft 52 are driven by means of suitable gears from the main drive of the machine and are so synchronized with respect to each other that the cam on shaft 65 will push the engaged end of the arbor 55 down (and thus raise the roller 63) a slight distance as the flange 6i, rotating in a clockwise direction (as viewed in Figs. 1 to 4) approaches the roller 63;

A divider plate '52, of the irregular shape shown in Figs. 11 and 1'7, is secured on a stub shaft above the inner end of the chute I3 and mounted for rotation in an inclined plane substantially parallel to the newspaper sections B in the chute 13. The shaftrfor the disc 72 is connected by bevel gears to a shaft 13 (Fig. 11) which in turn} is driven fromth main drive of the machine} The divider plate 12 has a long finger-like peripheral extension 82 at one side and a shorter peripheral extension 83 on the opposite side. The" latter shorter extension terminates in a slight outwardly-curved lip 84.

A driven shaft 14 (Figs. 1 to 4) carries a pair of cams l5 inside the side plates l5 and II respectively and thes cams l5 engage a pair of arms 16 respectively which are hinged at the bottom ends on a cross rod 11 and which support A coilspring a press bar 18 at their top ends. 89, having one end connected to the center of the press bar 18 and the other end anchored to a cross rod 90, holds the arms 15 against their cams l5.

' The manner in which the newspaper sections B are opened up one by one in order to receive the newspaper sections A and the manner in which each opened newspaper section B in turn is handled and removed from the end of the divider plate 12 is in raised position entirel out: of contact with the newspaper section B to be opened up and discharged from the chute l3 except for the extended finger portion 82. The outer'corner of this newspaper section B rests against the inner end 45 of the bar 45. The arms 16 will have been moved against the force of spring 19 by their cams l5 and caused the press bar 18 to bear against the adjacent face of the newspaper section B. The inner end 35 of the bar 45 now starts moving downwardly a short distance .pushing the corner of a'portion of the newspaper section B with it and causing the same to bulge outwardly into the machine between the bar end 45' and the press bar 18, as illustrated in Figs. 3 and 14. The finger 55, carried by the arm 53, next moves inwardly quickly and the wedge-shaped portion of the finger 56 moves into the bulge in the newspaper section. As the finger 56 reaches the end of its inward movement the supplemental finger 58 is engaged by the element 60 which causes the supplemental finger to move out quickly with respect to the main finger 56 as illustrated in Fig. 16 which increases the bulge in the corresponding portion of the newspaper section B to the extent of pulling the bulged half of the section out from under the end 45 of the bar 45. As the inner end 45 of the bar 45 approaches the end of its downward travel, its pin 80, in contact with thesloping bottom at the lower end of the groove 8|, pushes the end 45 inwardly until the end 45 no longer presses firml against the paper. The purpose of this is to enable the paper now to be pulled out from under the end 45 of the bar 45 whereupon the endof the bar 45' subsequently will move back up to its starting position for the next newspaper section. The return upward movement of the bar end 45 is produced by the action of the spring 63. The slot in the upper end of the link 49 (Fig. 14) enables the ban The newspaper sections B tend 45" to remain the raised position, with tthe pin-.80 contacting the uppcr end of the groove -,-8I until thevupward movementsof the link 49 r-againcauses-the bar end 4 5 to push downward- .ly. Nowithe press barJB moves inwardly while rthe short peripheral extension 183 of the divider plate @12 movesidownwardly (theidivider plate rotating counter-clockwise as viewed in Fig. 11) .to enter into the center of the opened newspaper sect-ion B, and to holdtheouter half portion in .the chute [3. The newspaper section B will vthenbe in theposi-tion illustrated in Fig. l. The ,rotatingnange =6! new engages the top edge of "the -inne half of the newspaper section B in ritspath and moves this over against the roller A33 'into the position illustrated in 1. The .roller tit-is raised so that-the engaged top porl'tion of -this half ofthe newspaper sectionB' is .pressedlbetween thecam-like member 5! and the .tro1lerc63. Further movement of the membe El eca-usesvthe engaged portion of the newspaper seclt-ion'Bt-to be pulled upwardly and inwardlyythus .pulling the bottom 1 fold of the newspaper section sup-out .of the chute 13.. While the newspaper section: is heldtin this positioirthe newspaper section A dropping down out of engagement with the driven rolls 38 andcompanion squeeze rel-ls e39 dropsintothe opened section B.

A pair of pick-up cams lasimilar in shape rand; size to the pick upwcamszli previously 'de-- scribed, are secured on the shaft it. A pair of squeeze rolls-8t similar to the squeeze rolls 24 and -39 are mountedon brackets 8| above the pick- --.up 0211115 79 respectively. The brackets 8i are mounted in the manner similar to the brackets 25;andw40 previously described. The pick-up came 19 rotate in counter-clockwise direction as viewed in Figs. ltd-4. As the pick-up earns .79 engage the-bottom fold of the outer news- ;paper section B (with-the newspaper sect-ion A rinsertedin final position in-the newspaper secstion B) the two sections are pulled between the squeeze rolls l9 and their companion-press rolls -80 as illustrated in FigsJZ and 3, and "finally the two newspaper sections 'are'delivered from the roams T51 and rolls 86 onto asuitable endless conveyor (notshown) and "this removed from the machine.
